Abstract

Dispositif et précédé de décontamination d'un produit liquide On fait d'abord passer les boues résiduaires dans une presse à tamis convoyeur 1 où elles subissent un essorage partiel avec une réduction considérable de leur volume. On obtient ainsi une couche relativement mince et régulière, que l'on décontamine ensuite au moyen d'un dispositif d'irradiation 2. Ce dispositif améliore le rendement économique, car du fait de la réduction du volume des boues résiduaires, il est possible d'utiliser la puissance du dispositif d'irradiation 2 d'une manière plus efficace. Application à la décontamination des boues résiduaires.
